Which ocular treatment is used for blurred vision due to anticholinergic effects when eye drops are indicated?

• A. Artificial tears
• B. Saline solution
• C. Pilocarpine 0.5% eye drops
• D. Corticosteroid eye drops

Answer: (C)

Anticholinergic drugs in the eye cause blurred vision by blocking muscarinic activity, leading to pupil dilation and loss of accommodation. To reverse this, you want a medication that activates muscarinic receptors in the eye. Pilocarpine is a direct muscarinic agonist; it constricts the pupil (miosis) and stimulates the ciliary muscle to contract, restoring accommodation and reducing the blur. Artificial tears or saline don’t address accommodation, and corticosteroid drops treat inflammation rather than reversing anticholinergic effects. Pilocarpine 0.5% eye drops best counteracts the blurred vision caused by anticholinergic effects.
